只上传一张图片的功能已经实现，上传两张图片就实现不了，代码段比较简单，麻烦大家指导一下：
上传图片的表单：
- PHP code
<?php
if ( isset($_GET['action']) && $_GET['action'] == "save" )
{
include_once('conn.php'); //连接数据库
include_once('uploadclass.php');//这个文件在下文会给出
$pic=$uploadfile; //第一张图片，已经可以正常上传
$pic2=$uploadfile2; //第二张，上传不了
$sql="insert into product (pic,pic2) values ('$pic','$pic2')";
$result=mysql_query($sql,$conn);
if (!$result)
{
echo mysql_error();
echo $sql;
exit;
}
else
{
echo"<Script>window.alert('congratulations,the product data inserted successful');location.href='index.php'</Script>";
}
mysql_close();
}
?>

Images_1:

<input type="hidden" name="MAX_FILE_SIZE" value="2000000" />
<br />
Images_2:
<input name="file2" type="file" value="Browse" />
<input type="hidden" name="MAX_FILE_SIZE" value="2000000" />
<p />
<input type="submit" value="upload this resource" name="upload" />
</form>
</body>
</html>
上传程序：uploadclass.php（此程序只能上传图片1，如果要能上传图片2，需要怎么加代码呢？）
- PHP code
<?php
$uploaddir = "../images/upfiles/";
$type=array("jpg","gif","bmp","jpeg","png");
$patch="aloesky/";
function fileext($filename)
{
return substr(strrchr($filename, '.'), 1);
}
function random($length)
{
$hash = 'CR-';
$chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
$max = strlen($chars) - 1;
mt_srand((double)microtime() * 1000000);
for($i = 0; $i < $length; $i++)
{
$hash .= $chars[mt_rand(0, $max)];
}
return $hash;
}
$a=strtolower(fileext($_FILES['file']['name']));
if(!in_array(strtolower(fileext($_FILES['file']['name'])),$type))
{
$text=implode(",",$type);
echo "You can only upload the following types of files:",$text,"<br /> <a href='upload_pro.php'>return and try again?click me</a>";
exit;
}
else{
$filename=explode(".",$_FILES['file']['name']);
do
{
$filename[0]=random(10);
$name=implode(".",$filename);
//$name1=$name.".Mcncc";
$uploadfile=$uploaddir.$name;
}
while(file_exists($uploadfile));
if (move_uploaded_file($_FILES['file']['tmp_name'],$uploadfile))
{
if(is_uploaded_file($_FILES['file']['tmp_name']))
{
echo "the Images Upload failed!";
}
else
{
echo "<center>Your file has been uploaded: </center><br><center><img src='$uploadfile' /></center>";
echo "<br><center><a href='upload_pro.php'>Continue to upload</a></center>";
}
}
}
?>
